The company has sought higher electricity tariff for the power produced from the Tilaiya plant due to increase in raw material and equipment cost as a result of rupee depreciation.
According to information available on the website of Central Electricity Regulatory Commission (CERC), the petition will come up for hearing on October 15.
Jharkhand Integrated Power Limited is a subsidiary of Reliance Power.
Reliance Power has already filed four petitions with the regulatory commission, seeking relief for its other UMPP at Sasan in Madhya Pradesh, due to a rise in construction cost and rupee depreciation.
